MARKET REVIEW

ALUMINA MARKET

From January to June 2013, the global capacity of alumina continued to increase. The increase in China’s

alumina capacity exceeded that of the international market. According to statistics, the global capacity

utilization rate of alumina was approximately 77.69% as at the end of June while that of China was

approximately 84.05%. In the first half of the year, the global output and consumption of alumina

were approximately 49.14 million tonnes and 48 million tonnes respectively, representing a year-on-

year increase of 2.82% and 6.93%, respectively. China’s output and consumption of alumina were

approximately 21.38 million tonnes and 23.00 million tonnes respectively, representing a year-on-year

increase of 12.17% and 21.56%, respectively. Imported alumina was approximately 1.65 million tonnes,

representing a year-on-year decrease of 33.20%.

In the first half of the year, the global alumina market witnessed an initial rise followed by a fall. The FOB

price of spot alumina of Australia hit a record high at USD347 per tonne and a record low at USD325

per tonne, with an average price of USD333 per tonne, representing a year-on-year increase of 4.89%.

The domestic market continued to experience an unqualified downward trend, with a record high and

a record low of domestic price of spot alumina at RMB2,578 per tonne and RMB2,472 per tonne,

respectively, with an average price of RMB2,536 per tonne, representing a year-on-year decrease of 3.47%.

PRIMARY ALUMINUM MARKET

From January to June 2013, the global capacity of primary aluminum continued to increase. As at

the end of June, the global capacity utilization rate of primary aluminum was approximately 85.67%,

while that of China was approximately 89.29%. In the first half of the year, the global output and

consumption of primary aluminum were approximately 24.50 million tonnes and 24.47 million tonnes,

respectively, representing a year-on-year increase of 6.24% and 5.93%, respectively. China’s output

and consumption of primary aluminum were 10.58 million tonnes and 10.60 million tonnes respectively,

representing a year-on-year increase of 11.49% and 10.42%, respectively.

2013 INTERIM REPORT

During the first half of 2013, there was a slowdown in the growth of demand from aluminum end-

customers and the global primary aluminum market saw excess supply. The problem of excess market

supply became more prominent in China. In the first half of the year, the price of three-month aluminum

futures at London Metal Exchange (LME) reached a record high at USD2,160 and a record low at

USD1,764 per tonne, with an average price of USD1,955 per tonne, representing a year-on-year decrease

of 7.61%. The price of three-month aluminum futures at Shanghai Futures Exchange (SHFE) reached a

record high at RMB15,350 per tonne and a record low at RMB14,240 per tonne, with an average price

of RMB14,885 per tonne, representing a year-on-year decrease of 7.62%.

ALUMINUM FABRICATION MARKET

In the first half of the year, the growth in the industry demand from aluminum product end-users

slowed down in line with a slow-down in the growth of the national economy. As a result, the growth

in the demand of aluminum fabrication slowed down. Meanwhile, the long fall in the prices of LME and

SHFE resulted in declining exports of aluminum fabrication. The scale and capacity of domestic aluminum

fabrication enterprises continued to expand and the standard of installed capacity continued to improve,

resulting in more and more intensified competitions in the aluminum fabrication market.

BUSINESS REVIEW

During the first half of 2013, the production and operation of the Company as well as the capacity

of production remained steady. The output of alumina amounted to 6.08 million tonnes, representing

a year-on-year increase of 1.84%; the output of alumina chemicals amounted to 0.76 million tonnes,

representing a year-on-year increase of 20.63%; the output of primary aluminum products amounted to

2.03 million tonnes, representing a year-on-year decrease of 0.49%; the output of coal amounted to 2.42

million tonnes; and power generation volume (excluding self-supply power plants) amounted to 4.041

billion kWh.

In the first half of the year, the world economy lacked momentum in recovery. The national economy was

under structural adjustment and transformation of the development model. The price of bulk commodities

in the globe fluctuated and kept declining due to factors such as the slowing down of economic growth.

The prices of the principal products of the Company kept declining. Confronted by the extremely hostile

market scenario, the Company adopted a series of proactive and effective countermeasures:

1. The Company furthered its efforts in restructuring and strategic transformation. In the first half

of 2013, the Company adjusted its development strategies after analyzing the elements of the

overall structural challenges of the aluminum industry and its development needs diligently. It

aspired to strengthen the industry through vigorous acquisitions and development of high-quality

bauxite resources, and leveraged such advantages over resources to develop the core business of

alumina. It optimized and developed the aluminum business which provided the Company with

integrated advantages over coal-electricity-aluminum production. In the first half of the year, the

Company completed the transfer of the aluminum fabrication assets and the assets of the alumina

production line of Guizhou Branch, which improved its structures of assets and liabilities effectively

and reduced the debt to asset ratio accordingly.

2. The Company further promoted the transformation of operations and upgraded its management.

In the first half of 2013, transformation of operations of the Company had been carried out

which covered preliminarily in 25 entities and 14 professional areas. The Company emphasized the

transformation from “being professional” to “being systematic”, from “being micro” to “macro”.

The target of the upgrading of management altered from major entities to auxiliary entities, from

branches to workshops and teams. The Company prioritized operational transformation and set its

quantitative aim of controlling costs and increasing profits according to its production operation,

financial management, sales management, procurement management etc. The percentage of

excellent class alumina increased by 4.55 percentage points as compared with the corresponding

period of the preceding year. The consolidated energy consumption decreased by 7.92% as

compared with the corresponding period of the preceding year. The rate of completion of

aluminum ingots AL99.70 grew by 0.11 percentage point as compared with the corresponding

period of the preceding year. The consumption of alternating current in aluminum ingot

production decreased by 109kWh/t as compared to the corresponding period of the preceding

year. The consolidated rate of qualification of anode carbon block increased by 0.12 percentage

point as compared with the corresponding period of the preceding year. The maintenance

expenses of equipment decreased by 7.80% as compared with the corresponding period of the

preceding year. The Company strengthened its mine facilities and enhanced its management.

It also enhanced the proportion of its self-developed mines, the rate of the integrated use of

associated resources and streamlined the settlement of the ore cost. Meanwhile, it maintained the

supply of its imported ore proactively and made efforts to expand the channels of ore supply in

the places other than Indonesia.

2013 INTERIM REPORT

3. The Company enhanced self-innovation and accelerated achievement transformation. In the first

half of 2013, the Company revised its technological development plan and identified its aim of

technological development by consolidating its current business conditions and development

strategy. The Company focused on the introduction and implementation of major technological

projects such as the new series process of production, the consolidated technology of high sulphur

bauxite production of alumina, the consolidated technology of safe and efficient bauxite mining

under complicated conditions, the technology of consolidated utilization of high-iron-content Bayer

red mud and co-products of iron and aluminum (高鐵拜耳法赤泥及鐵鋁共生礦綜合利用技術) and

the technological research and development of electrolytic cells of ultra-high capacity. It continued to

transform and apply mature technologies, such as the highly efficient Bayer process technology, the

“201” technology and the new cathode steel bar technologies.

4. The Company enhanced its marketing and improved its capacity of cost reduction. In the first half

of 2013, facing a severe market trend, the Company improved its study and analysis of the market

to enhance its knowledge of the market. It explored many profit-generating models from various

pricing mechanisms. It maintained a reasonable level of stock and increased its benefits by leveraging

the fluctuations of the domestic and international spots and futures markets. It also launched its

futures and options businesses and developed hedge and risk hedging ability of futures. Leveraging

futures as hedging tools, it kept itself unscathed by the unfavorable impacts of declining market

prices. The realised price of alumina was higher than the average domestic spot price by RMB63 per

tonne, while that of realised price of aluminum products marked higher than the price of Shanghai

Futures Exchange by RMB84 per tonne. The Company purchased bulk materials in a centralized

manner by centralizing the negotiation and signing contracts separately. The cost of the procurement

was thus reduced and the supply was secured. The Company introduced lean procurement, set up

the “Evaluation Methods of the Procurement System” (採購體系評價辦法), and established a cross-

level and cross-department tracking and supervisory system and a security mechanism.

5. The Company secured funding and strictly controlled finance costs. It kept diversifying its financing

activities into various kinds and various channels and obtained sufficient banking facilities and debt

financing instruments registered at NAFMII (交易商協會). As at the end of June, the unutilized

banking facilities and debt financing instruments of the Company amounted to RMB92.5 billion

and RMB20.0 billion respectively. The Company strengthened the management of current assets

and current liabilities to speed up the recovery of the receivables and raise the efficiency of capital

utilization. The Company implemented numerous measures at the same time, which ensured a

net operating cash inflows of RMB1.662 billion, representing a year-on-year increase of RMB3.477

billion. As at the end of June, the weighted average interest rate of the interest-bearing loans

fell by 0.11 percentage point as compared to the beginning of this year. The annual capital

expenditure budget of 2013 was significantly reduced by 45% as compared to the actual amount

during the same period of 2012.

6. The Company launched the reform of “market-orientation and open manner” and stimulated

impetus within the enterprise. In the first half of 2013, the Company completed the recruitments

of general managers for five enterprises, such as Shanxi Huaze, implemented an accountability

system on the management team in accomplishing business objective for risk premium, the

clarification of 3-year operational objectives, the empowerment of the general managers in

personnel distribution, work distribution, appraisal and allocation, as well as the comprehensive

organization of production and operations according to the principles of market-orientation,

legal and regulatory compliance and safety and stability. A market-based personnel selection

and designation system and a target-based responsibility management system were formed

preliminarily. The market orientation reform proved to be successful at the primary stage, with

much stronger impetus in operation and management and improving corporate performance. In

August 2013, the Company completed the market-orientation reforms of two enterprises, namely

Lanzhou Branch and Baotou Aluminum Co., Ltd.

7. The Company strived to safety production and environment protection. As the Company expanded

its scale, there was a further increase in energy and resource consumption. In the meantime,

the quality of bauxite and coal declined. All the above imposed greater and greater pressure to

safety production and environment protection. In the first half of 2013, the Company continued

to enhance the establishment of an accountability system of safety, environmental protection and

health. It continued to improve and enhance the level of the standardization of safe production.

It strengthened the consolidated penalty of violations of regulations and the elimination of

potential risks. It also introduced a consolidated governance of carbon enterprises and the safety

management of mines. It strengthened the education and trainings of safety and optimized plans

for onsite management of entity enterprises.

OUTLOOK AND PROSPECTS

In the second half of 2013, the world economy saw a lacklustre recovery with uncertainties abound.

China’s economy, albeit being steady as a whole, enters a stage of structural adjustment as it grapples

with overcapacity and other contradictions. There was no alleviation for the oversupply of the Company’s

principal products and the market is likely to turn more gloomy. The Company will continue to introduce

structural adjustment, deepen the reform of “market-orientation and open manner”, and push forward

the transformation of operations and improvement of its management. Furthermore, it will strengthen

its capital management, maintain safety production and endeavor to reduce losses significantly for a

turnaround, which is the business target for the year. The principal tasks are as follows:

1. The Company will further make structural adjustment according to its strategy. The Company

will further research on plans and measures of assets restructuring according to its long-term

development and short-term benefits. The Company will suspend production of, merge and

transfer those production lines or enterprises where breakeven could not be achieved. The energy

segment, subject to safety, will improve the mining technology and the quality and quantity of coal

and aspire to strike a balance between production and sales. The Company will reduce costs by

means of technology. It will accelerate the industrial implementation of new technologies, such as

the dissolution of sodium carbon clinker and the application of highly conductive electrolyte. The

Company will strive to develop the entire flotation of desulphurization technology. The Company

will continue to proceed with the Simandou Project, accelerate the exploration process of the

bauxite mining project of the joint venture in Laos and meet the target of the increase in bauxite

production of the joint venture in Indonesia. The Company will accelerate the implementation of

the preliminary work of the alumina project in West Kalimantan, Indonesia. It will speed up the

preparation for the transfer of production capacity in Guizhou Branch and the integrated coal-

electricity-aluminum project.

2. The Company will expedite the technological innovation and reduce the cost through technology.

3. The Company will further introduce the “market orientation and open manner” reform. Such

reform triggered the enterprise’s momentum and vitality. The Company will launch the reform of

marketization in several key enterprises on the basis of summarizing the experience drawn from

the enterprise reform seriously. The Company will issue the “Human Resources Plan for 2013-2015

of Aluminum Corporation of China Limited*” (《中國鋁業股份有限公司2013-2015年人力資源規

劃》) which emphasizes the training and the enrollment of talents specialized in mining, energy

and overseas development.

4. The Company will continue to transform its operations and refine its management

comprehensively. It will strengthen its operational transformation and daily management, and

further promote better management across the basic managing units in the enterprise with a focus

to strengthen the capability of CBS core team and speed up the development of a standardized

CBS module. It will further improve the management in mines and reinforce production safety and

construction of the mines to improve the self-supply of the ore.

5. The Company will strength its market researches to increase sales profits. The Company intends to

strengthen its market research so as to improve its market foresight. It will reinforce its operational

strategies and methods to capture favorable commercial opportunities. It will strengthen its

development in the international market to diversify the sources of its business income and profits.

It will continue to boost marketing efforts in the coking coal market and strive to commence

coking coal fabrication, trading and export so as to increase the integrated benefits brought by

coking coal trading. In addition, it will step up efforts in achieving a balanced product delivery

and allocate its resources reasonably to reduce the cost of transportation. The Company will make

greater efforts in consolidating negotiations and separating the execution of contracts for bulk

materials, further increase the proportion of centralized coal procurement to reduce its logistics

cost and formulate and optimize its logistic system development plans.

6. The Company will enhance capital management and safeguard its funding. It will keep on

adhering to the concept of ‘’cash is king’’. With this in mind, it will prepare various financing

plans to ensure financing via multi-channels at a low cost. It will proceed with the issue of

perpetual loans to meet its financing target. It will try to secure a relatively significant increase in

the net cash inflow from operating activities year on year, maintain its asset-to-liability ratio within

a reasonable target and effectively control the financial expenses.

RESULTS OF OPERATIONS

The Group’s net loss attributable to the shareholders of the parent for the first half of 2013 was RMB596

million, among which losses from continuing operations amounted to RMB832 million, while profits from

discontinued operation amounted to RMB236 million (please refer to note 6 to the financial statements

for details of discontinued operation). The Group’s net loss attributable to the shareholders of the parent

for current period decreased significantly by 81.68% from RMB3,253 million of the corresponding period

of the preceding year. This was mainly attributable to the Group’s strict control of cost and expenses

in every aspect, and efforts in enhancement of the gross profit of its major businesses. Besides, the

Group recognised gain on the acquisition of Ningxia Energy and its operating profit. Moreover, the

Group recognised gain on deemed disposal of the equity interest in Jiaozuo Wanfang and gain from the

disposal of aluminium fabrication segment and alumina production line of Guizhou Branch.

REVENUE

The Group’s revenue generated from continuing operations for the first half of 2013 was RMB71,113

million, representing an increase of RMB4,344 million or 6.51% from RMB66,769 million of the

corresponding period of the preceding year. This was mainly attributable to the increase in external

trading volume of the Group, and the newly added revenue of coal and electricity contributed by the

newly acquired subsidiary of Ningxia Energy.

COST OF SALES

Cost of sales of the Group from continuing operations was RMB69,768 million for the first half of 2013,

representing an increase of RMB3,332 million or 5.02% from RMB66,436 million of the corresponding

period of the preceding year, which was 1.49 percentage points lower than the growth in revenue from

continuing operations. This was mainly attributable to the increase in the external trading volume of the

Group, and the newly added sales of coal and electricity contributed by the newly acquired subsidiary of

Ningxia Energy. However, as the Group strictly controlled the cost and expenses in various aspects, the

production cost of the principal products fell to some extent as compared with the corresponding period

of the preceding year.

In the first half of 2013, the production cost of alumina, the major product of the Group, fell by 8.52%

as compared with the corresponding period of the preceding year. In particular, through operational

transformation and strengthening of fundamental management, the fall in consumption of raw materials

and fuel drove the cost to decrease by 6.01%, the drop of the price of raw materials and fuel drove the

cost to decrease by 3.87%, while the rise in the price of bauxite drove the cost up by 1.20%.

In the first half of 2013, the production cost of primary aluminium, the major product of the Group,

fell by 6.64% as compared with the corresponding period of the preceding year. In particular, through

operational transformation and strengthening of fundamental management, the drop of price in raw

materials, fuel and power drove a decrease of 6.08% in cost, and the decrease in the consumption of

raw materials, fuel and power drove a decrease of 0.44% in cost, and the change in producing cost

drove a decrease of 0.12% in the cost.

SELLING AND DISTRIBUTION EXPENSES

The Group’s selling and distribution expenses from continuing operations for the first half of 2013

were RMB847 million, representing a decrease of RMB52 million or 5.78% from RMB899 million of the

corresponding period of the preceding year. This was mainly attributable to the decrease in the expenses

of transportation and loading due to the Group’s strict control of the cost in various aspects.

GENERAL AND ADMINISTRATIVE EXPENSES

General and administrative expenses from continuing operations for the first half of 2013 of the Group

were RMB1,257 million, representing an increase of RMB44 million or 3.63% from RMB1,213 million

of the corresponding period of the preceding year. Excluding the general and administrative expenses

of the newly acquired subsidiary of Ningxia Energy, the general and administrative expenses decreased

by 8.33% as compared to the general and administrative expenses of the corresponding period of the

preceding year, which was mainly attributable to the Group’s strict control of the cost and expenses in

various aspects.

OTHER GAINS, NET

In the first half of 2013, other net gain of the Group from continuing operations was RMB1,741 million,

representing an increase of RMB1,919 million as compared to other net loss of RMB178 million of the

corresponding period of the preceding year. This was mainly attributable to the gain on acquisition of

Ningxia Energy and gain from loss of control of Jiaozuo Wanfang through deemed disposal.

Given the major factors described as above, the Group’s operating profit from continuing operations

was RMB1,426 million for the first half of 2013, representing an increase of RMB3,183 million from the

operating loss of RMB1,757 million of the corresponding period of the preceding year.

million, representing an increase of RMB566 million or 27.75% from RMB2,040 million of the

corresponding period of the preceding year. This was mainly attributable to the significant increase in

scale of interest-bearing borrowings contributed by the consolidation of Ningxia Energy. Excluding the

finance costs of the newly acquired subsidiary of Ningxia Energy, the finance costs increased by 7.22%,

among which the increase in the average interest-bearing borrowings caused an increase of 20.33% in

the net finance costs as compared with the corresponding period of the preceding year, but the increase

was offset by the fall in the weighted average interest rate and other factors by 13.11%.

For the first half of 2013, the Group’s share of profits of joint ventures and associates from continuing

operations amounted to RMB292 million, representing an increase of RMB136 million from RMB156

million of the corresponding period of the preceding year, primarily due to newly added share of profits

of joint ventures and associates as a result of the consolidation of Ningxia Energy.

INCOME TAX

The Group’s income tax expense from continuing operations for the first half of 2013 was negative

RMB34 million, representing an increase of RMB691 million from negative RMB725 million of the

corresponding period of the preceding year. This was mainly attributable to the fact that the Group

recognised deferred tax assets related to the tax loss generated in the first half of 2012, while most of

the tax losses of the Group for the first half of 2013 have not been recognised as deferred tax assets.

PROVISION FOR INVENTORY IMPAIRMENT

On June 30, 2013, the Group assessed the net realizable value of its inventories. For the inventory

relevant to aluminum products, the assessment was made with comprehensive consideration of the

coordination scheme of the production and sales between alumina enterprises and aluminum enterprises

within the Group, and the factors including the financial budget, turnover period of inventory, the

purpose of the Company to hold the inventory and the influence of events subsequent to the balance

sheet date, the assessment was made on the net realizable value of its inventories based on the

estimated selling price of the finished goods available for sale. For the inventory held by the energy

segment, after comprehensively considering the cooperative scheme on production and sale along the

chain of the photovoltaic industry, the Group unanimously calculated with the market price for the most

immediate period. The net realizable value of the inventory which was not sold after the period was

evaluated at the market price of the finished goods less the cost and expenses required for the whole

process of a product to be ready for sale.

The provisions for inventory impairment for inventories held as of June 30, 2013 amounted to RMB1,203

million, representing a decrease of RMB204 million as compared with the provisions for impairment of

RMB1,407 million at the beginning of the year. The decrease was caused by increase in net provisions

and reversal of RMB195 million, the addition of RMB180 million from the consolidation of Ningxia

Energy, the written-off for the period of RMB450 million, and the decrease of RMB129 million from the

disposal of Jiaozuo Wanfang and disposal of the aluminum fabrication segment.

The Company has always adopted the same approach to determine the net realizable value of the inventories

and the provisions of inventories impairment on a consistent basis for the relevant accounting policy.

CORPORATE GOVERNANCE

The Articles of Association, the Terms of Reference of the Audit Committee, the Terms of Reference of

the Supervisory Committee and the Code of Conduct Regarding Securities Transactions by the Directors,

Supervisors and Relevant Employees form the framework for the code of corporate governance practices

of the Company. The Board has reviewed its corporate governance documents and internal control

guidelines, and is of the view that such documents have incorporated most of the principles and code

provisions in the “Code on Corporate Governance Practices” (the “CG Code”) as set out in Appendix

14 to the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the

“Hong Kong Listing Rules”) and the requirements under the Internal Control Guidelines stipulated by the

Shanghai Stock Exchange.

During the reporting period, saved as disclosed below, the Board is of the opinion that the Company

has complied with the code provisions of the CG Code and the requirements under the Internal Control

Guidelines stipulated by the Shanghai Stock Exchange.

Rule A.2.1 of the CG Code provides that, inter alia, the roles of chairman and chief executive should

be separated and should not be performed by the same individual. The chairman and chief executive

of the Company were served by one person. On May 9, 2013, the Board considered and approved the

resolution in respect of the cancellation of the position of chief executive officer for the Company’s

operational and management needs with effect from the conclusion of the Board meeting. As a result,

the Company has since complied with the requirements of Rule A.2.1 of the CG Code.

include at least three independent non-executive directors. Pursuant to the Articles of Association and

the Terms of Reference of the Audit Committee, the audit committee must comprise a minimum of three

independent non-executive directors. Before the proposal of electing members of the fifth session of the

Board at the 2012 annual general meeting of the Company, the Company had not selected a candidate

for independent non-executive director. Therefore, since June 27, 2013, the number of independent

non-executive directors and members of the audit committee of the Company had been lower than the

minimum number as required in Rule 3.10(1) and Rule 3.21 of the Hong Kong Listing Rules. On August

30, 2013, the Company appointed Mr. Wu Zhenfang as an independent non-executive director and a

member of the audit committee of the Company. As such, the Company had been in compliance with

Rule 3.10(1) and Rule 3.21 of the Hong Kong Listing Rules.

CODE OF CONDUCT FOR SECURITIES TRANSACTIONS BY THE DIRECTORS, SUPERVISORS AND RELEVANT EMPLOYEES

For clarity, the Company has adopted a Code of Conduct Regarding Securities Transactions by the

Directors, Supervisors and Relevant Employees (the “Required Standards”) on terms no less exacting than

the required standard of dealings set out in the “Model Code for Securities Transactions by Directors

of Listed Companies” in Appendix 10 to the Hong Kong Listing Rules. Some employees who are likely

to be in possession of unpublished price sensitive information of the Group shall be in compliance with

the Required Standards. All Directors, Supervisors and Relevant Employees, upon specific enquiries, have

confirmed that they have complied with the Required Standards during the six months ended June 30,

2013.

2013 INTERIM REPORT

Overall disposal of equity in aluminum fabrication entities

Sapa and Guizhou Chalco) by way of open tender at Beijing Equity Exchange. On June 7, 2013,

in relation to non-competition, including:

the aluminum fabrication business from Chinalco, and acquire the pseudo-boehmite business from

Chinalco within a certain period of time following the listing of the Company’s A shares.

Page 41: 2013 INTERIM RESULTS ANNOUNCEMENT · 2014-09-01 · Market Review 6 Business Review 7 Outlook and Prospects 11 Interim Results 13 Interim Dividend 13 Management’s Discussion and

40

Besides, the Company provided additional undertakings:

On August 22, 2011, the Company issued a letter of undertaking of Aluminum Corporation of

China Limited* to resolve the horizontal competition with Jiaozuo Wanfang Aluminum Company

Limited (hereafter, “Jiaozuo Wanfang”) in the aluminum business (中國鋁業股份有限公司關於解

決與焦作萬方鋁業股份有限公司電解鋁業務同業競爭的承諾函), pursuant to which it undertook

to make its best endeavors to eliminate by proper means the competition in aluminum business

with Jiaozuo Wanfang within five years.

There is no competition in aluminum fabrication business between the Company and Chinalco.

Up till now, both Shanxi Aluminum Factory, a wholly-owned subsidiary of Chinalco, and the

Shandong branch of the Company had minor activities in the pseudo-boehmite market. However,

as the pseudo-boehmite business is not among the principal activities of the Company, the

revenue from sales of that segment made up a relatively low portion of the Company’s revenue

and as the sales locations of pseudo-boehmite of Shandong branch and Shanxi Aluminum Factory

are different, the competition between Chinalco and the Company in respect of pseudo-boehmite

business is limited.

Since the market conditions for pseudo-boehmite are immature, Chinalco does not propose to

inject its pseudo-boehmite business to the Company’s portfolio for the time being.

In April 2013, Jiaozuo Wanfang issued 169,266,914 A shares through non-public offering to five

companies including Manulife Teda Fund Management Co., Ltd. (泰達宏利基金管理有限公司) and

Yinhua Fund Management Co., Ltd. (銀華基金管理有限公司). After the completion of the non-

public offering of A shares, the Company’s shareholding in Jiaozuo Wanfang fell from 24.002%

to 17.75%. On July 24, 2013, Jiaozuo Wanfang held the third extraordinary meeting for 2013 to

consider and approve the proposed amendments to the articles of association and the proposed

election of additional two independent directors. Jiaozuo Wanfang became a public company

without controlling shareholders and actual controller. There was no competition within the same

business between the Company and Jiaozuo Wanfang any longer.

When conditions become mature, both Chinalco and the Company will continue to duly

implement the matters undertaken within the time limit.

2013 INTERIM REPORT

7. OTHER SIGNIFICANT EVENTS

On August 24, 2012, the twenty-ninth meeting of the fourth session of the Board of the

Company resolved to propose to issue not more than 1.45 billion A shares in the PRC to qualified

legal persons, natural persons, or other legally qualified investors. On October 12, 2012, SASAC

approved such resolution. At the 2nd Extraordinary General Meeting for 2012, the second Meeting

for Holders of A Shares for 2012 and the second Meeting for Holders of H Shares for 2012

held on October 12, 2012, the shareholders also considered and approved the non-public issue

plan and related matters. On December 7, 2012, Issuance Examination Committee of the China

Securities Regulatory Commission (CSRC) approved the application to issue A shares through non-

public offering, and the application of issuing A shares through non-public offering was approved

unconditionally. On March 14, 2013, the Company received the approval from CSRC to issue new

shares of no more than 1.45 billion through non-public offering, effective within the six months

from the date of the approval. As at the date of the publication of this report, no such issuance

had occurred.

For details of the matter, please refer to the announcements of the Company dated October 12,

2012 and March 14, 2013.

Change in the shareholding of Jiaozuo Wanfang

As of December 31, 2012, the registered capital of Jiaozuo Wanfang, the non-wholly-owned

subsidiary of the Company was RMB480,176,100. The Company held 24.002% of its shares as the

largest shareholder. In April 2013, Jiaozuo Wanfang issued 169,266,914 A shares through non-

public offering to five companies including Manulife Teda Fund Management Co., Ltd. (泰達宏利

基金管理有限公司) and Yinhua Fund Management Co., Ltd. (銀華基金管理有限公司). After the

completion of non-public offering of A shares, the registered capital of Jiaozuo Wanfang increased

to RMB649,443,014, and the Company’s shareholding in Jiaozuo Wanfang fell from 24.002%

INDEPENDENT REVIEW REPORT

To the shareholders of Aluminum Corporation of China Limited

(Established in the People’s Republic of China with limited liability)

Introduction

We have reviewed the interim financial information set out on page 44 to 136, which comprise the

condensed consolidated statement of financial position of Aluminum Corporation of China Limited (the

“Company”) and its subsidiaries (together the “Group”) as at June 30, 2013 and the related condensed

consolidated statements of comprehensive income, changes in equity and cash flows for the six-month

then ended, and a summary of significant accounting policies and other explanatory notes. The Main

Board Listing Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited

require the preparation of a report on interim financial information to be in compliance with the relevant

provisions thereof and International Accounting Standard 34 Interim Financial Reporting (“IAS 34”). The

directors of the Company are responsible for the preparation and presentation of this interim financial

information in accordance with IAS 34. Our responsibility is to express a conclusion on this interim

financial information based on our review. Our report is made solely to you, as a body, in accordance

INDEPENDENT REVIEW REPORT (CONTINUED)

Scope of review

We conducted our review in accordance with International Standard on Review Engagements 2410,

Review of Interim Financial Information Performed by the Independent Auditor of the Entity. A review of

interim financial information consists of making inquiries, primarily of persons responsible for financial

and accounting matters, and applying analytical and other review procedures. A review is substantially

less in scope than an audit conducted in accordance with International Standards on Auditing and

consequently does not enable us to obtain assurance that we would become aware of all significant

matters that might be identified in an audit. Accordingly, we do not express such opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the interim

financial information is not prepared, in all material respects, in accordance with IAS 34.

2. BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES

(a) Basis of preparation

The interim condensed consolidated financial statements for the six months ended June 30,

2013 have been prepared in accordance with International Accounting Standard (“IAS”) 34

Interim Financial Reporting.

The interim condensed consolidated financial statements do not include all the information

and disclosures required in the annual financial statements, and should be read in

conjunction with the Group’s annual financial statements as at December 31, 2012.

Going concern

As at June 30, 2013, the Group’s current liabilities exceeded its current assets by

approximately RMB30,382 million (December 31, 2012: RMB34,837 million). The directors

of the Company have considered the Group’s available sources of funds as follows:

• The Group’s expected net cash inflows from operating activities in 2013;

• Unutilised banking facilities of approximately RMB92,472 million as at June 30, 2013,

of which amounts totalling RMB76,905 million will be subject to renewal during the

next 12 months. The directors of the Company are confident that these banking

facilities could be renewed upon expiration based on the Group’s past experience and

good credit standing; and

• Other available sources of financing from banks and other financial institutions given

the Group’s credit history.

and Interpretations and amendments) that are effective from January 1, 2013:

New accounting policy adopted by the Group in relation to Ningxia Energy

Mining rights and mineral exploration rights

The Group’s mining rights include coal, bauxite and other mining rights.

Mining rights are initially recorded at cost which include payments of consideration for

extraction rights, exploration and other direct costs.

Amortisation of bauxite and other mining rights is provided on a straight-line basis according

to the shorter of the expiration date of the mining certificate and the mineable period of

natural resources. Estimated useful lives of the majority of the mining rights range from 3 to

30 years.

Mining rights and mineral exploration rights (Continued)

Coal mining rights are amortised on a unit-of-production basis over the economically

recoverable reserves of the mine concerned.

Mineral exploration rights are initially recorded at the cost of the acquisition and adopt

the same method as the one for the mining rights to amortise since the exploration rights

convert to the mining rights and begin to produce.

New and revised IFRSs adopted by the Group

IAS 1 Presentation of Items of Other Comprehensive Income — Amendments to IAS 1

The amendments to IAS 1 introduce a grouping of items presented in other comprehensive

income (“OCI”). Items that could be reclassified (or “recycled”) to profit or loss at a future

point in time (e.g., net gain on hedge of net investment, exchange differences on translation

of foreign operations, net movement on cash flow hedges and net loss or gain on available-

for-sale financial assets) now have to be presented separately from items that will never

be reclassified (e.g., actuarial gains and losses on defined benefit plans and revaluation of

land and buildings). The amendments affected presentation only and have no impact on the

Group’s financial position or performance.

IAS 1 Clarification of the requirement for comparative information (Amendment)

This amendment to IAS 1 clarifies the difference between voluntary additional comparative

information and the minimum required comparative information. An entity must include

comparative information in the related notes to the financial statements when it voluntarily

provides comparative information beyond the minimum required comparative period. The

additional voluntarily comparative information does not need to be presented in a complete

set of financial statements.

An opening statement of financial position (known as the ‘third balance sheet’) must be

presented when an entity applies an accounting policy retrospectively, makes retrospective

restatements, or reclassifies items in its financial statements, provided any of those changes

has a material effect on the statement of financial position at the beginning of the

preceding period. The amendment clarifies that a third balance sheet does not have to be

accompanied by comparative information in the related notes. Under IAS 34, the minimum

items required for interim condensed financial statements do not include a third balance

sheet. The amendment has no impact on the Group.

IAS 19 Employee Benefits (Revised)

The IASB has issued numerous amendments to IAS 19. The revised standard introduces

significant changes in the accounting for defined benefit pension plans including removing

the choice to defer the recognition of actuarial gains and losses. Other changes include

modifications to the timing of recognition for termination benefits and disclosures of

defined benefit plans. These amendments have no impact on the Group’s financial position

or performance.

IAS 28 Investments in Associates and Joint Ventures (as revised in 2011)

As a consequence of the new IFRS 11 Joint Arrangements, and IFRS 12 Disclosure of

Interests in Other Entities, IAS 28 Investments in Associates, has been renamed IAS 28

Investments in Associates and Joint Ventures, and describes the application of the equity

method to investments in joint ventures in addition to associates. These amendments have

no impact on the Group’s financial position or performance.

IFRS 1 Government Loans — Amendments to IFRS 1

These amendments require first-time adopters to apply the requirements of IAS 20

Accounting for Government Grants and Disclosure of Government Assistance, prospectively

to government loans existing at the date of transition to IFRSs. Entities may choose to

apply the requirements of IFRS 9 (or IAS 39, as applicable) and IAS 20 to government

loans retrospectively if the information needed to do so had been obtained at the time of

initially accounting for that loan. The exception would give first-time adopters relief from

retrospective measurement of government loans with a below-market rate of interest. The

amendments have no impact on the Group.

IFRS 7 Disclosures — Offsetting Financial Assets and Financial Liabilities — Amendments to IFRS 7

The amendments require an entity to disclose information about rights to set-off financial

instruments and related arrangements (e.g., collateral agreements). The disclosures would

provide users with information that is useful in evaluating the effect of netting arrangements

on an entity’s financial position. The new disclosures are required for all recognised financial

instruments that are set off in accordance with IAS 32 Financial Instruments: Presentation.

The disclosures also apply to recognised financial instruments that are subject to an

enforceable master netting arrangement or similar agreement, irrespective of whether the

financial instruments are set off in accordance with IAS 32. As the Group is not setting

off financial instruments in accordance with IAS 32 and does not have relevant offsetting

arrangements, the amendments do not have any impact on the Group.

IFRS 10 Consolidated Financial Statements and IAS 27 Separate Financial Statements

IFRS 10 establishes a single control model that applies to all entities including special

purpose entities. IFRS 10 replaces the parts of previously existing IAS 27 Consolidated and

Separate Financial Statements that dealt with consolidated financial statements and SIC 12

Consolidation — Special Purpose Entities.

IFRS 10 changes the definition of control such that an investor controls an investee when

it is exposed, or has rights, to variable returns from its involvement with the investee and

has the ability to affect those returns through its power over the investee. To meet the

definition of control in IFRS 10, all three criteria must be met, including: (a) an investor has

power over an investee; (b) the investor has exposure, or rights, to variable returns from its

involvement with the investee; and (c) the investor has the ability to use its power over

the investee to affect the amount of the investor’s returns. IFRS 10 has no impact on the

consolidation of investments held by the Group.

IFRS 11 Joint Arrangements

IFRS 11 replaces IAS 31 Interests in Joint Ventures and SIC 13 Jointly Controlled Entities

— Non-Monetary Contributions by Venturers. IFRS 11 addresses only two forms of joint

arrangements, i.e., joint operations and joint ventures, and removes the option to account

for joint ventures using proportionate consolidation. Instead, joint arrangements that meet

the definition of a joint venture must be accounted for using the equity method. Application

of this new standard has no impact on the financial position and financial performance of

the Group because there are no changes in classification of the Group’s joint arrangements

after the Group assessed its investments in joint ventures and the Group’s joint ventures are

accounted for using equity method of accounting.

IFRS 12 Disclosure of Interests in Other Entities

IFRS 12 includes all of the disclosures that were previously in IAS 27 related to consolidated

financial statements, as well as all of the disclosures that were previously included in

IAS 31 and IAS 28. These disclosures relate to an entity’s interests in subsidiaries, joint

arrangements, associates and structured entities. None of these disclosure requirements are

applicable for interim condensed consolidated financial statements, unless significant events

and transactions in the interim period require that they are provided. Accordingly, the Group

has not made such disclosures.

IFRS 13 Fair Value Measurement

IFRS 13 establishes a single source of guidance under IFRS for all fair value measurements.

IFRS 13 does not change when an entity is required to use fair value, but rather provides

guidance on how to measure fair value under IFRS when fair value is required or permitted.

The application of IFRS 13 has not materially impacted the fair value measurements carried

out by the Group.

IFRS 13 also requires specific disclosures on fair values, some of which replace existing

disclosure requirements in other standards, including IFRS 7 Financial Instruments:

Disclosures. Some of these disclosures are specifically required for financial instruments by

IAS 34.16A(j), thereby affecting the interim condensed consolidated financial statements

period. The Group provides these disclosures in Note 4.

IFRIC 20 Stripping Costs in the Production Phase of a Surface Mine

This interpretation applies to waste removal (stripping) costs incurred in surface mining

activity during the production phase of the mine. The interpretation addresses the initial

measurement and subsequent measurement of the benefit from the stripping activity.

According to the Group’s assessment, this standard has no material impact on the financial

position and performance of the Group.

This amendment clarifies that an entity that ceased applying IFRS in the past and chooses,

or is required, to apply IFRS, has the option to re-apply IFRS 1. If IFRS 1 is not re-applied, an

entity must retrospectively restate its financial statements as if it had never ceased applying

IFRS.

IAS 16 Property, Plant and Equipment

This amendment clarifies that major spare parts and servicing equipment that meet the

definition of property, plant and equipment are not inventories.

IAS 32 Financial Instruments: Presentation

This amendment clarifies that income taxes arising from distributions to equity holders are

accounted for in accordance with IAS 12 Income Taxes. The amendment removes existing

income tax requirements from IAS 32 and requires entities to apply the requirements in IAS

12 to any income tax arising from distributions to equity holders. The amendment does not

have any impact on the interim condensed consolidated financial statements for the Group,

as there is no tax consequences attached to cash or non-cash distribution.

IAS 34 Interim Financial Reporting

The amendment clarifies the requirements in IAS 34 relating to segment information for

total assets and liabilities for each reportable segment to enhance consistency with the

requirements in IFRS 8 Operating Segments. Total assets and liabilities for a reportable

segment need to be disclosed only when the amounts are regularly provided to the chief

operating decision maker and there has been a material change in the total amount

disclosed in the entity’s previous annual consolidated financial statements for that reportable

segment. As the Group included the disclosure of total segment assets and liabilities as

reported to the chief operating decision maker in prior year’s financial statements, the

amendment does not have any impact on the interim condensed consolidated financial

statements.

The Group has not early adopted any other standard, interpretation or amendment that has

been issued but is not yet effective.

3. SIGNIFICANT ACCOUNTING JUDGEMENTS AND ESTIMATES

The preparation of the interim condensed consolidated financial statements requires management

to make judgements, estimates and assumptions that affect the reported amounts of revenues,

expenses, assets and liabilities, and the accompanying disclosures, and the disclosure of contingent

liabilities. Uncertainty about these judgements, assumptions and estimates could result in outcomes

that require a material adjustment to the carrying amounts of assets or liabilities affected in future

periods.

In preparing these interim condensed consolidated financial statements, the significant judgements

and estimates made by management in applying the Group’s accounting policies and the key

sources of estimation uncertainty were the same as those that applied to the consolidated financial

statements for the year ended December 31, 2012, except the new estimates adopted by the

Group after the acquisition of Ningxia Energy in January 2013 as disclosed in note 22(a) to the

financial statements:

Coal reserve estimates and unit-of-production amortisation for coal mining

rights

Engineering estimates of the Group’s coal reserves are inherently imprecise and represent

only approximate amounts because of the subjective judgements involved in developing such

information. There are authoritative guidelines regarding the engineering criteria that have to be

met before estimated coal reserves can be designated as “proved” and “probable”. Proved and

probable coal reserve estimates are updated on regular basis and have taken into account recent

production and technical information about each mine. In addition, as prices and cost levels

change from year to year, the estimate of proved and probable coal reserves also changes.

4.1 Financial risk management

(a) Financial risk factors

The Group’s activities expose it to a variety of financial risks: market risk (including

foreign currency risk, cash flow and fair value interest rate risk and commodity price

risk), credit risk and liquidity risk.

The interim condensed consolidated financial statements do not include all financial

risk management information and disclosures required in the annual financial

statements, and should be read in conjunction with the Group’s annual financial

statements for the year ended December 31, 2012.

There have been no changes in the risk management department or in any risk

management policies since last year end. Compared to last year end, there was no

material change in the status of market risk and credit risk.

(b) Liquidity risk

Compared to December 31, 2012, there was no material change in the contractual

undiscounted cash outflows for financial liabilities, except for the net increase

in short-term loans and borrowings amounting to RMB5,671 million which were

primarily for meeting working capital need; and the addition and the repayment

of long-term bank and other loans amounting to RMB2,752 million and RMB4,879

million, respectively.

As at June 30, 2013, the Group had total banking facilities of approximately

RMB158,552 million (December 31, 2012: RMB161,761 million), of which amounts

totalling RMB66,080 million have been utilised as at June 30, 2013 (December 31,

2012: RMB64,819 million). Banking facilities of approximately RMB106,610 million

will be subject to renewal within the next 12 months. The directors of the Company

are confident that such banking facilities can be renewed upon expiration based on

their past experience and good credit standing.

In addition, as at June 30, 2013, the Group had credit facilities through its primary

aluminum futures agent at the London Metal Exchange amounting to USD116 million

(equivalent to RMB716.73 million) (December 31, 2012: USD94 million (equivalent to

RMB590.84 million)), of which USD24.49 million (equivalent to RMB151.32 million)

(December 31, 2012: USD1.03 million (equivalent to RMB6.47 million)) has been

utilised. The futures agent has the right to adjust the related credit facilities.

Fair value hierarchy

The Group uses the following hierarchy for determining and disclosing the fair values of

financial instruments:

Level 1: Fair value measured based on quoted (unadjusted) prices in active markets for

identical assets or liabilities.

Level 2: Fair value measured based on valuation techniques for which all inputs which

have a significant effect on the recorded fair value are observable, either

directly or indirectly.

Level 3: Fair value measured based on valuation techniques for which any inputs which

have a significant effect on the recorded fair value are not based on observable

market data.

For financial instruments that are recognised at fair value on a recurring basis, the Group

determines whether transfers have occurred between levels in the hierarchy by re-assessing

the categorisation (based on the lowest level input that is significant to the fair value

measurement as a whole) at the end of each reporting period.

5. REVENUE AND SEGMENT INFORMATION (CONTINUED)

(b) Segment information

The presidents of the Company (formerly “the Company’s Executive Committee”) have

been identified as the chief operating decision-makers. They are responsible for the review

of the internal reports in order to allocate resources to operating segments and assess their

performance.

The presidents consider the business from a product perspective comprising alumina,

primary aluminum and aluminum fabrication for the Group’s manufacturing business, which

is identified as separate reportable operating segments. In addition, the Group’s trading

business is identified as a separate reportable operating segment. The Group’s operating

segments also include corporate and other operating activities.

However, as disclosed in notes 2(a) and 6 to the financial statements, the Group has

disposed of its equity interests and assets in the Aluminum Fabrication Segment on June 27,

2013. Accordingly, the Aluminum Fabrication Segment has been classified as a discontinued

operation and was excluded from the segment information for the period ended June 30,

2013.

In addition, the Company acquired an aggregate of 70.82% equity interest in Ningxia

Energy on January 23, 2013. Ningxia Energy is principally engaged in research and

development, production and operation of energy products, mainly includes coal mining,

electricity generation by thermal power, wind power and solar power, new energy related

equipment manufacturing business, and construction and operation of coal aluminum

integration. After the acquisition of Ningxia Energy, the presidents have identified Ningxia

Energy and other energy related operations, formerly included in corporate and other

operating segments, as energy segment in accordance with IFRS 8 Operating Segments.

(b) Segment information (Continued)

As a result of the above changes in segment structure, the comparative figures of segment

information for the period ended 30 June, 2012 were restated accordingly.

The presidents assess the performance of operating segments based on profit or loss

before income tax in related periods. Unless otherwise stated below, the manner of

assessment used by the presidents is consistent with that applied in these interim condensed

consolidated financial statements. Management has determined the operating segments

based on the reports reviewed by the presidents that are used to make strategic decisions.

The Group’s five reportable operating segments are summarised as follows:

• The alumina segment, which consists of mining and purchasing bauxite and other

raw materials, refining bauxite into alumina, and selling alumina both internally to

the Group’s aluminum plants and externally to customers outside the Group. This

segment also includes the production and sale of chemical alumina and metal gallium.

• The primary aluminum segment, which consists of procuring alumina and other raw

materials, supplemental materials and electricity power, smelting alumina to produce

primary aluminum which is sold to the Group’s internal aluminum fabrication plants

and external customers. This segment also includes the production and sale of carbon

products and aluminum alloy and other aluminum products.

5. REVENUE AND SEGMENT INFORMATION (CONTINUED)

(b) Segment information (Continued)

For the six months ended June 30, 2013, revenues from continuing operations of

approximately RMB9,509 million (for the six months ended June 30, 2012 from continuing

operations: RMB11,997 million (restated)) are derived from entities directly or indirectly

owned or controlled by the PRC government, including Chinalco. These revenues are mainly

attributable to the alumina, primary aluminum, energy and trading segments. There is no

other individual customer with transactions of more than 10% of the Group’s revenue

during the period ended June 30, 2013.

6. DISCONTINUED OPERATION

On June 9, 2013, the Company entered into an equity interest transfer agreement (“Aluminum

Fabrication Interests Transfer Agreement”) with Chinalco, pursuant to which the Company

transferred to Chinalco its equity interests in (a) six subsidiaries: (1) 90.03% equity interest in

Chalco Henan Aluminum Co., Ltd.(中鋁河南鋁業有限公司) (“Henan Aluminum”); (2) 60% equity

interest in Chalco Southwest Aluminum Co., Ltd.(中鋁西南鋁板帶有限公司); (3) 100% equity

interest in Chalco Southwest Aluminum Cold Rolling Company Ltd.(中鋁西南鋁冷連軋板帶有

限公司); (4) 56.86% equity interest in Huaxi Aluminum Company Ltd.(華西鋁業有限責任公司);

(5) 93.30% equity interest in Chalco Ruimin Co., Ltd.(中鋁瑞閩鋁板帶有限公司); and (6) 100%

equity interest in Chalco Qingdao Light Metal Co., Ltd.(中鋁青島輕金屬有限公司) (“Qingdao Light

Metal”) (collectively known as “Aluminum Fabrication Subsidiaries”), (b) a joint venture: 50% equity

interest in Chalco Sapa Aluminum Products (Chongqing) Co., Ltd. (中鋁薩帕特種鋁材(重慶)有限公司)

(“Chalco Sapa”); and (c) an associate: 40% equity interest in Guizhou Chalco Aluminum Co., Ltd. (貴

州中鋁鋁業有限公司) (“Guizhou Chalco”) ((b) and (c) together known as “Aluminum Fabrication

Investments”) (see Note 8(d)). In addition, the Company entered into the Aluminum Fabrication

Assets Transfer Agreement with Northwest Aluminum Fabrication Plant, a subsidiary of Chinalco, on

June 6, 2013, pursuant to which the Company transferred the net assets in Northwest Aluminum

Fabrication Branch of the Company (西北鋁加工分公司) (“Aluminum Fabrication Branch”) to

Northwest Aluminum Fabrication Plant. The above transactions were completed on June 27, 2013.

NOTES TO UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)For the six months ended June 30, 2013

(Amounts expressed in thousands of RMB unless otherwise stated)

6. DISCONTINUED OPERATION (CONTINUED)

The Aluminum Fabrication Subsidiaries and Aluminum Fabrication Branch form the Aluminum

Fabrication Segment of the Group. Pursuant to the Aluminum Fabrication Interests Transfer Agreement

and the Aluminum Fabrication Assets Transfer Agreement, the consideration thereof was determined

with reference to independent valuation undertaken by professional valuers recognised in the PRC of

the net asset of the respective entities/branch as at December 31, 2012, adjusted to give effect to the

changes in net assets value from the valuation date (December 31, 2012) to the disposal date.

As an adhere condition to disposal of certain of the Aluminum Fabrication Subsidiaries, as at December

31, 2012, the Company’s entrusted loans to Henan Aluminum and Qingdao Light Metal were

transferred to Chinalco with a nominal principal amount up to RMB3 billion (“Transferred Loan to

Chinalco”), and the appraisal value of such loans was taken as the basis for the consideration.

After giving adjustment to the change in the net assets value from the valuation date (December

31, 2012) to the disposal date regarding the Aluminum Fabrication Subsidiaries and the Aluminum

Fabrication Branch, the aggregate consideration for the disposal of the Aluminum Fabrication Segment

and the Transferred Loan to Chinalco was finalized at RMB6,314.5 million. The disposal of the Aluminum

Fabrication Segment and the Transferred Loan to Chinalco shall be considered in their totality.

The disposal of Aluminum Fabrication Segment can optimise the asset structure, lower the debt to

asset ratio, improve the debt portfolio of the Group, increase the operating cash flows of the Group

and strengthen the re-financing ability of the Group, which is beneficial for the Group to focus on the

development of quality resources and develop its business relating to the quality resources, so as to move

towards the forefront of the industry chain and the high-end of the value chain.

Since the Aluminum Fabrication Segment was a component of the Group’s business, representing a

separate major line of business with separately identifiable operations and cash flows, it is classified

as a discontinued operation. Accordingly, the results of the Aluminum Fabrication Segment were

separately reported as a “discontinued operation” in the interim condensed consolidated statement of

comprehensive income for the period ended June 30, 2013. In addition, the gain recognised on the

disposal of the Aluminum Fabrication Segment was also included in results of discontinued operation.
